Give them pizza, apparently. They’ll starve.
The perfect way to slice a pizza
They can’t think about sharing a pizza, for example, without falling headlong into the mathematics of how to slice it up. “We went to lunch together at least once a week,” says Mabry, recalling the early 1990s when they were both at Louisiana [...]

Rhett’s got a post up on parallax, and how you can use this effect to measure distance: Parallax, what is it good for? He’s got some pictures showing the effect of viewing from different vantage points.
The other thing you can do with such photos is to make stereograms, and I’ve taken the liberty [...]

sevensixfive: Circles
This is an open question: What is this fractal? It’s a method for filling a 2D plane with circles in an orderly way – circles made of circles, all the way down. There are published examples of similar systems, like the Apollonian Gasket, the Kleinian Groups, Indra’s Pearls, but I’ve never seen this [...]
